Abstract:
A method of wireless communications includes determining a period of time to trigger inter-radio access technology (IRAT) cell reselection. The method also includes adjusting the period of time accordingly, in which the adjusting is based on a target cell signal strength, the target cell belonging to a different RAT than a source cell. The period of time may also be determined based on the source cell signal strength and/or target cell signal strength, and adjusted accordingly.
Abstract:
The scheduling rate of the synchronization channel (SCH) base station identity code (BSIC) is adapted based on target cell signal metric such as, the signal quality and/or signal strength. The scheduling rate is decreased when the target cell metric is below a first threshold value and is increased when the target cell metric is above a second threshold value. The scheduling rate may also be adapted based on a serving cell signal metric.
Abstract:
A user equipment (UE) is configured to maintain an updated frequency list for pseudo-fast return handover. The UE receives a frequency list for pseudo fast return when the UE is in an idle mode in a first radio access technology (RAT). When the UE is in a connected mode in a second RAT, the list is updated based on actual UE inter- and intra-frequency measurements of the first RAT during mobility.
Abstract:
A user equipment (UE) considers both the signal strength in time slot zero and the signal quality of the downlink traffic time slots when determining whether to send an IRAT measurement report to trigger IRAT handover to GSM.
Abstract:
A user equipment (UE) may perform an advanced inter radio access technology (IRAT) measurement of a target cell when the UE transitions from an idle state to a connected state of a serving cell to reduce delay. In such instances, the UE compares the serving cell signal metric to a threshold. The advanced measurement may be performed when the serving cell signal metric, e.g., serving cell received signal code power (RSCP), is below the threshold.
Abstract:
A method for wireless communication performed by a user equipment (UE) includes transmitting, to a first network, a first message comprising a first measurement gap configuration, a measurement gap reconfiguration, a selection from a measurement gap pool, or a measurement gap release. The method also includes receiving a second message, from the first network. The second message may configure a measurement gap, reconfigure a measurement gap, or release a measurement gap. The second message may also suspend data communication from the UE during a configured measurement gap. The method additionally includes suspending communication with the first network during the configured measurement gap. The communication may be suspended to save power, tune away for a multiple subscriber identity module (MSIM) of the UE, or measure a neighbor cell.
Abstract:
Methods, systems, and devices for wireless communications are described. The method includes transmitting, to a base station based on a parameter of a configuration of the UE, a first HARQ feedback configuration or a request to modify the configuration of the UE, or both, the configuration of the UE including a carrier aggregation configuration and receiving, from the base station based on transmitting the first HARQ feedback configuration or request to modify the configuration of the UE, or both, a second HARQ feedback configuration or reconfiguration.
Abstract:
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a channel state information (CSI) measurement and reporting protocol for dynamic spectrum sharing (DSS) in a wireless communication network. In some aspects, a BS may transmit control messages periodically and aperiodically that configure a UE to perform signal quality measurements and transmit signal quality reports. When the UE receives a periodic control message, the UE may perform signal quality measurements on both a multimedia broadcast single frequency network (MBSFN) subframe and a non-MBSFN subframe of a frame received from the BS. When the UE receives an aperiodic control message, the UE may perform a signal quality measurement on either a MBSFN subframe or a non-MBSFN subframe. The UE may generate and transmit signal quality reports to the BS periodically and aperiodically corresponding to the received periodic and aperiodic control messages, respectively.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first communication that includes information to facilitate selection and/or switching of carrier aggregation or multi-connectivity for a first cell group and a second cell group. The UE may receive, based at least in part on transmitting the first communication, a second communication that configures and/or switches carrier aggregation or multi-connectivity for the first cell group and the second cell group. Numerous other aspects are provided.
